下载对话框中的文件名有的是正确的中文也有是乱码，而且对话框会弹出两次

Question

加Response.Charset = "UTF-8"
Response.ContentEncoding = System.Text.Encoding.Default
就可以了，我也正郁闷为什么点打开时会再出一次确认框呢~~~~~~~~~

Answer 1

参考一下
HttpContext.Current.Response.AppendHeader("Content-Disposition","attachment;filename=export.xls");
HttpContext.Current.Response.Charset ="UTF-8";
HttpContext.Current.Response.ContentEncoding =System.Text.Encoding.Default;

Answer 2

HttpContext.Current.Response.Charset ="UTF-8";
应该是能解决的

Answer 3

用Response.AddHeader("Content-Disposition", "inline; filename=" + System.Convert.ToChar(34) + filename + System.Convert.ToChar(34))
Response.ContentType = "application/zip"
可解决二次对话问题！！！

Answer 4

private void ToEXCEL(System.Web.UI.Control ctl) 
{ 
Response.Charset="GB2312"; 
Response.AppendHeader("Content-Disposition","attachment;filename=myExcel.xls");  
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.ContentType = "application/ms-excel"; ctl.Page.EnableViewState = false; 
System.IO.StringWriter tw = new System.IO.StringWriter(); 
System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(tw);  ctl.RenderControl(hw);  Response.Write(tw.ToString()); 
Response.End(); 
}

Answer 5

贴出来看看，实在不行设一下IE设置里的高级，总是以UTF-8发送Url是否打钩。

Answer 6

代码如下： Response.AppendHeader("Content-Disposition","attachment;filename="+HttpUtility.UrlEncode(myExcel)+".xls"); 
Response.Charset="";  
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.ContentType = "application/ms-excel";
ctl.Page.EnableViewState = false; 
System.IO.StringWriter tw = new System.IO.StringWriter(); 
System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(tw); 
ctl.RenderControl(hw); 
Response.Write(tw.ToString()); 这种是下载的保存对话框在2000系统下显示正确的中文，而在XP系统下是乱码，对话框仍然是弹出两次

Answer 7

public static void DownloadFile( System.Web.UI.Page refPage, string _FilePath)
{
try
{
string MyContentType = "";
if(!System.IO.File.Exists(_FilePath)){
throw(new Exception("不存在的文件"));
}
Stream iStream=new FileStream(_FilePath,FileMode.Open,FileAccess.Read,FileShare.Read); long lngFileLength=iStream.Length;
FileInfo fileinfo = new FileInfo(_FilePath);
String FileName = fileinfo.Name;
switch ( FileName.Substring( FileName.LastIndexOf( "." ), 4 ) )
{
case ".xls":
MyContentType = "application/vnd.ms-excel";
break;
case ".doc":
MyContentType = "application/msword";
break;
case ".htm":
MyContentType = "text/html";
break;
default:
MyContentType = "application/zip";
break;
}


refPage.Response.Clear();
refPage.Response.AddHeader( "Content-Type", MyContentType );
refPage.Response.AddHeader("Content-Disposition", "inline;filename="+ System.Convert.ToChar(34) + System.Web.HttpUtility.UrlEncode( System.Text.Encoding.UTF8.GetBytes( FileName ) ) + System.Convert.ToChar(34) );
refPage.Response.AddHeader("Content-Length", fileinfo.Length.ToString() );
refPage.Response.Flush(); byte[] Buffer;
bool ClientClosed=false;
int BufferLength=Convert.ToInt32(System.Configuration.ConfigurationSettings.AppSettings["BufferLength"]);

int Len=1;             

while (Len>0 && ClientClosed==false)
{
Buffer= new Byte[BufferLength];
Len = iStream.Read(Buffer, 0, BufferLength);
refPage.Response.OutputStream.Write(Buffer,0,Len);
refPage.Response.Flush();
ClientClosed=!refPage.Response.IsClientConnected;
}
iStream.Close();
iStream=null;
refPage.Response.End();
}
catch( Exception excep )
{
throw(excep);

}
}

Answer 8

我们在下载时处理是将文件截取前32个字节,这样的话就不会错了.(如果不想这样做处理的话,可以UPDATE一下系统,由系统自己去做吧.)

Answer 9

我不是很懂qiren5761(杞人）的意思，请指教

Answer 10

我的：
            filename = Request.QueryString("title") & ".xls"
            filename = System.Web.HttpUtility.UrlEncode(System.Text.Encoding.UTF8.GetBytes(filename))            Response.ContentType = "application/vnd.ms-excel"
            ' 从Content-Type header中去除charset设置
            Response.Charset = ""
            Response.AddHeader("Content-Disposition", "attachment;filename=" & System.Convert.ToChar(34) & filename & System.Convert.ToChar(34))
            Response.Charset = "UTF-8"
            Response.ContentEncoding = System.Text.Encoding.Default            Me.EnableViewState = False
            Dim tw As New System.IO.StringWriter
            Dim hw As New System.Web.UI.HtmlTextWriter(tw)            DataGrid1.RenderControl(hw)
            Response.Write(tw.ToString())
            Response.End()
你还是加上filename = System.Web.HttpUtility.UrlEncode(System.Text.Encoding.UTF8.GetBytes(filename))吧

Answer 11

不过直接打开后，excel里面的文件名还是乱的，保存打开就没问题，谁有办法？呵呵~~

Answer 12

乱码的问题原来和“IE设置里的高级，总是以UTF-8发送Url是否打钩”这个有关。算是解决了。
